Japanese researchers have mapped vast reserves of rare earth elements in deep-sea mud, enough to feed global demand on a "semi-infinite basis," according to a new study.
The deposit, found within Japan's exclusive economic zone waters, contains more than 16 million tons of the elements needed to build high-tech products ranging from mobile phones to electric vehicles, according to the study, released Tuesday in the journal Scientific Reports.
[...] The finding extrapolates that a 2,500-sq. km region off the southern Japanese island should contain 16 million tons of the valuable elements, and "has the potential to supply these metals on a semi-infinite basis to the world," the study said.
The area reserves offer "great potential as ore deposits for some of the most critically important elements in modern society," it said.
The report said there were hundreds of years of reserves of most of the rare earths in the area surveyed.

Sad thing is, as with most resources, if supply goes up so will the willingness to use more of those resources. No one needs more than 640kb of memory, after all.

Bad example as 640 KB used to be the size of a fridge, and is now microscopic.
We'll see if it holds true if electricity from nuclear fusion hits 1 cent per kilowatt-hour.

"Sad" because we need to mourn all those exploited bytes and tons of rare earths? All I can say is that if we manage to increase our supply of rare earths by a factor of a million while reducing its cost by a similar factor, there's not a lot of sadness to be had in that.
